Technical Field

[0001] The present application relates to the technical field of bedding products, and in particular to a sleep monitoring pad. Background Art

[0002] The quality of sleep is an important factor affecting the quality of life, and snoring is a health problem that many people have during sleep. Data shows that the proportion of male snorers and female snorers in the population is as high as 52.2% and 34.2% respectively. Long-term snorers or those who snore severely are often accompanied by sleep apnea syndrome (OSA). More than 1 billion people suffer from OSA worldwide. Snoring / OSA is closely related to our health. Data shows that OSA is highly correlated with major diseases such as stroke, hypertension, coronary heart disease, depression, and diabetes. Over time, it can lead to various diseases and memory loss at the mildest, and even cause the loss of life at the worst.

[0003] For the above-mentioned snoring / OSA problems, sleep monitoring can be used for prevention and intervention. Existing sleep monitoring equipment mainly includes medical equipment and portable equipment.

[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0052] like Figure 1-Figure 6As shown, an embodiment of the present application provides a sleep monitoring pad, which includes a flexible pad 1, and the flexible pad 1 includes a main body layer 11, a piezoelectric sensor 12 and a first cable 13. The main body layer 11 is a flexible sheet structure, and the main body layer 11 is provided with a mounting groove 111, and the mounting groove 111 is arranged as a through groove that penetrates the thickness direction of the main body layer 11, and the mounting groove 111 extends along the length direction of the main body layer 11. By setting the mounting groove 111, the local thickness of the main body layer 11 is reduced, and the local strength of the main body layer 11 is weakened; the piezoelectric sensor 12 is arranged in the mounting groove 111, and is used to collect sleep data. The piezoelectric sensor 12 is arranged in a strip-shaped structure extending along the length direction of the main body layer 11, which can not only match the thickness of the piezoelectric sensor 12 with the thickness of the main body layer 11, so that the sleep monitoring pad remains flat as a whole, but also reduce the constraint of the main layer 11 on the piezoelectric sensor 12, so that the piezoelectric sensor 12 can be deformed freely, and the sensitivity of the piezoelectric sensor 12 is improved. sensitivity; the mounting groove 111 is arranged close to the first edge of the main layer 11, and accordingly, the piezoelectric sensor 12 is close to the first edge of the main layer 11, which can not only make the main layer 11 form a continuous and flat supporting area as much as possible, but also make it easier for the piezoelectric sensor 12 to locate the monitoring part, so as to better collect sleep data; one end of the first cable 13 is electrically connected to the output end of the piezoelectric sensor 12, and the other end extends beyond the edge of the main layer 11 to facilitate the connection between the sleep monitoring pad and external equipment (for example, power supply equipment, communication equipment or server, etc.). That is to say, except for a piezoelectric sensor 12, the inside of the sleep monitoring pad does not have other electronic components such as a microphone, which can reduce the psychological burden of the user when using it, thereby improving the user experience and ensuring the sleep quality.

[0053] In addition, the sleep monitoring pad provided in the embodiment of the present application can be directly laid on a supporting surface such as a bed for use. That is to say, it does not need to be worn or in direct contact with the body when used. Only the sleep monitoring pad needs to be laid on the bed to collect and analyze the user's sleep data imperceptibly, achieving zero burden and providing a better experience. The sleep monitoring pad is a flexible pad 1 with a single or multi-layer structure as a whole, which can not only improve the comfort of use of the sleep monitoring pad, but also facilitate the folding and storage of the sleep monitoring pad. When the sleep monitoring pad is a flexible pad 1 with a multi-layer structure, the layers can be connected to each other by bonding (for example, using double-sided tape or glue, etc.) to avoid introducing other connecting parts and affecting the overall comfort of the sleep monitoring pad.

[0054] Furthermore, the thickness of the sleep monitoring pad (thickness of the flexible pad 1) is 2mm to 4mm, for example, the thickness of the sleep monitoring pad is 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm or 4mm, etc., which can ensure both the strength of the sleep monitoring pad itself and the monitoring effect of the sleep monitoring pad. When the thickness of the sleep monitoring pad is less than 2mm, the overall strength of the sleep monitoring pad is insufficient, and it is easy to be torn or damaged during use; when the thickness of the sleep monitoring pad is greater than 4mm, the thickness of the sleep monitoring pad is too large, resulting in the sensitivity of the sleep monitoring pad being difficult to meet the requirements, and it will also affect the comfort of use and the convenience of folding the sleep monitoring pad.

[0055] Furthermore, the sleep monitoring mat also includes a main control box 2, which is arranged outside the edge of the main layer 11. The main control box 2 is connected to the end of the first cable 13 away from the piezoelectric sensor 12, and is used to receive and transmit monitoring data of each sensor (for example, the piezoelectric sensor 12, etc.) to the outside. In other words, the main control box 2 is arranged on the outside of the sleep monitoring mat, thereby simplifying the internal circuit structure of the sleep monitoring mat, so that the sleep monitoring mat has higher convenience of use and better user experience.

[0056] Specifically, a microcontroller unit (MCU), a communication module (e.g., 4G, WiFi, or Bluetooth, etc.) and an indicator light may be provided inside the main control box 2. The microcontroller unit is used to receive and read the signal output by the sensor, the communication module is used to transmit the signal to the outside, and the indicator light is used to indicate various working states of the sleep monitoring pad.

[0057] Furthermore, the main control box 2 is communicatively connected with the cloud server, that is, the main control box 2 transmits the signal output by the sensor to the cloud server for calculation and processing, which can not only realize basic sleep monitoring such as sleep staging, sleep efficiency, falling asleep and waking up, but also obtain physiological indicators such as breathing and heart rate in real time, realize in-depth monitoring of user sleep data, and thus provide monitoring indicators such as snoring and OSA.

[0058] Furthermore, a light sensor 21 is provided in the main control box 2 to monitor the light level of the sleeping environment, so as to more comprehensively grasp the sleep data. Specifically, the main control box 2 can be provided with a through hole or a transparent window through which light can pass, and the light sensor 21 is accommodated inside the main control box 2. After the external light passes through the through hole or the transparent window, it irradiates the light sensor 21.

[0059] Furthermore, the sleep monitoring pad also includes a second cable 3, one end of which is connected to the main control box 2, and the other end is provided with a power connector 5 (for example, a USB connector 5, etc.), so that the sleep monitoring pad can be connected to an external power supply, thereby continuously monitoring the user's sleep data.

[0060] Furthermore, the second cable 3 is provided with a temperature and humidity sensor 4 to monitor the temperature and humidity of the sleeping environment, so as to grasp the sleep data more comprehensively; a gap is arranged between the temperature and humidity sensor 4 and the main control box 2 to prevent the heat emitted by the main control box 2 from affecting the temperature and humidity, resulting in the monitoring data of the temperature and humidity sensor 4 being unable to accurately reflect the sleeping environment; the temperature and humidity sensor 4 is arranged to be a columnar structure extending along the length direction of the second cable 3, so that the temperature and humidity sensor 4 maintains a high consistency with the second cable 3, thereby improving the integrity and appearance of the sleep monitoring pad.

[0061] like Figure 4-Figure 6 As shown, the sleep monitoring pad is a pillow pad, which is placed under the pillow for use. The first edge is the lower edge of the main layer 11 (i.e., the edge of the main layer 11 close to the neck), so that the piezoelectric sensor 12 can better bear the gravity of the head, thereby better collecting BCG / respiration and other signals; an amplifier circuit 121 can be provided at the output end of the sensor to make the output signal of the sensor have a larger amplitude, improve the quality of the signal, and facilitate subsequent transmission and processing of the signal; a wire groove for accommodating the first cable 13 can be provided inside the sleep monitoring pad, and the end of the sensor and the first cable 13 are limited by the wire groove to reduce the movement amplitude of the first cable 13, thereby preventing the connection between the first cable 13 and the sensor from loosening and affecting the accuracy of sleep data collection; the first cable 13 extends out of the second edge of the main layer 11 along the end of the wire groove to reduce the bending deformation of the first cable 13 and improve the overall flatness of the sleep monitoring pad.

[0062] Furthermore, a bending portion 131 is provided at a position of the first cable 13 away from the piezoelectric sensor 12 , and a wire clip 132 is provided at the bending portion 131 . The wire clip 132 is embedded in the wire groove, thereby forming a reliable limit for the end of the first cable 13 and effectively reducing the movement range of the first cable 13 .

[0063] In one embodiment, the main body layer 11 is provided with a first wire groove (not shown in the figure), one end of the first wire groove is connected to the installation groove 111, and the other end extends in a direction away from the first edge and passes through the edge of the main body layer 11, that is, the first wire groove and the installation groove 111 are roughly L-shaped structures; the output end of the sensor is accommodated in the first wire groove, and at least a part of the first cable 13 is accommodated in the first wire groove. In this way, the first wire groove and the installation groove 111 form a whole, which can simplify the overall structure of the sleep monitoring pad, reduce the number of parts, and avoid the first cable 13 and the main body layer 11 from forming a laminated structure, further reducing the overall thickness of the sleep monitoring pad.

[0064] In another embodiment, the sleep monitoring pad includes a wiring board 14, which is connected (for example, bonded) to the main body layer 11; the wiring board 14 is provided with a second wire groove 141, one end of the second wire groove 141 is connected to the installation groove 111, and the other end extends in a direction away from the first edge and passes through the edge of the wiring board 14, that is, the projection of the second wire groove 141 and the installation groove 111 on the surface of the main body layer 11 is roughly L-shaped; the output end of the sensor is accommodated in the second wire groove 141, and at least a part of the first cable 13 is accommodated in the second wire groove 141. In this way, the depth of the second wire groove 141 is increased by setting the wiring board 14, so that a more reliable limit can be formed for the first cable 13 to prevent the first cable 13 from escaping from the second wire groove 141.

[0065] Specifically, the wiring board 14 is a flexible sheet structure, and the wiring board 14 is stacked on one side of the main layer 11, and the wiring board 14 and the main layer 11 are connected to each other by bonding; the wiring board 14 is stacked on the lower surface of the main layer 11 to keep the upper surface of the sleep monitoring pad as flat as possible, thereby providing comfortable and stable support. It can be understood that the wiring board 14 can also be arranged on the upper surface of the main layer 11; the wiring board 14 extends along the width direction of the sleep monitoring pad, and the edge of the wiring board 14 is aligned with the edge of the sleep monitoring pad to form a neat edge contour; the wiring board 14 can be made of waterproof material to provide protection for the internal circuit and improve the waterproof and moisture-proof performance of the sleep monitoring pad.

[0066] Furthermore, a wire pressing plate 15 is provided on both sides of the main body layer 11, the output end of the piezoelectric sensor 12 is sandwiched between the two wire pressing plates 15, and at least a portion of the first cable 13 is sandwiched between the two wire pressing plates 15. The output end of the piezoelectric sensor 12 and the first cable 13 are fixed by providing the wire pressing plate 15 to prevent the first cable 13 and the output end of the piezoelectric sensor 12 from moving relative to each other during use or folding, thereby ensuring the reliability of the connection between the first cable 13 and the piezoelectric sensor 12. The wire pressing plate 15 is a hard sheet structure with low brittleness, which can not only reliably fix the first cable 13, but also does not affect the folding and storage of the sleep monitoring pad.

[0067] Specifically, when the sleep monitoring pad is not provided with a wiring board 14, the main layer 11 is sandwiched between two wire pressing plates 15, and the two wire pressing plates 15 are respectively connected to the upper and lower sides of the main layer 11; when the sleep monitoring pad is provided with a wiring board 14, the main layer 11 and the wiring board 14 are sandwiched between the two wire pressing plates 15, one of the wire pressing plates 15 is connected to the main layer 11, and the other wire pressing plate 15 is connected to the wiring board 14 and the main layer 11 at the same time.

[0068] Furthermore, the sleep monitoring pad also includes a coating layer 16, which is a flexible sheet structure, and is disposed on the upper and lower sides of the main layer 11, that is, the coating layer 16 and the main layer 11 are stacked along the thickness direction of the sleep monitoring pad, and there are two coating layers 16, which completely cover the upper and lower sides of the main layer 11. By providing the coating layer 16, the internal circuit can be sealed to prevent damage to the internal circuit, and strength and support can be provided, so that the sleep monitoring pad can be smoothly unfolded, and the sleep monitoring pad can be prevented from being deformed such as wrinkles, which affects the monitoring effect of the piezoelectric sensor 12.

[0069] Furthermore, the sleep monitoring pad further includes a surface layer 17, which is a flexible sheet structure, and is disposed on the side of the covering layer 16 away from the main layer 11, that is, the surface layer 17 and the covering layer 16 are stacked along the thickness direction of the sleep monitoring pad, and the number of the surface layers 17 is two, and the two surface layers 17 respectively completely cover the side of the covering layer 16 away from the main layer 11. By providing the surface layer 17, the appearance performance of the sleep monitoring pad can be improved, for example, a soft and comfortable surface is formed, or an easy-to-clean surface is formed.

[0070] A multi-layer structure of a sleep monitoring pad provided in an embodiment of the present application can be specifically referred to as follows: the main layer 11 adopts a PC sheet with a thickness of about 0.2 mm; the wiring board 14 adopts an SRC diving material with a thickness of about 2.0 mm; the wire pressing plate 15 adopts a PC sheet with a thickness of about 0.2 mm; the covering layer 16 adopts PU bass with a thickness of about 1.0 mm; the surface layer 17 adopts PU semi-silicon leather with a thickness of about 0.5 mm.

[0071] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
